Police were called to break up a brawl that erupted outside WIN Stadium after the Illawarra rugby grand final between Camden and Avondale on Saturday.
A fight broke out outside the ground between Avondale and Camden spectators immediately after the first grade match, which was won by Camden.
Around 15 people were involved in the fight.
Witnesses called police who arrived to disperse the crowd soon after.
A police spokesman said no-one was seriously injured in the brawl and no arrests were made.
The brawl followed an earlier incident during the second grade match in which an Avondale player and a Camden spectator were involved in an altercation, with stadium security staff separating the pair.
